3 Claims.

This invention relates to closures for washing bowls, sinks, plumbing iixtures and the like, and more particularly to the plug and sleeve construction used in connection therewith.

One of the objects is to provide a construction wherein the plug will be maintained and positioned in any of Aits moved positions without requiring any further manipulation of the plug.

Another object is to provide a plug which is normally maintained in its sleeve against unauthorized removal, but which can be removed and reinserted by a slight manipulation of the plug.

Another object is to provide a construction which is simple and inexpensive to manufacture and easy and efficient to operate.

Other objects will become apparent as this description progresses.

Fig. 7 is a cross sectional view taken on line 'Il-'l of Fig. 6.

Referring to the construction shown in Fig. l, the usual wash basin 20 has a water discharge orice 22 and an overflow passage 24. The upper end of the orifice is beveled to form a seat for the flange portion 26 of the metal sleeve 28. interposed between the ilange portion and the basin is a gasket 21. The sleeve 28 has a pair of oppositely positioned openings 30 which communicate with the overilow passage 24. The lower portion of the sleeve is threaded as at 32 and extends through the bottom of the basin. Threadedly engaged with the lower portion of the sleeve is a discharge pipe 33 which leads to a sewer fixture not shown. The discharge pipe locks said sleeve in uid tight engagement with the wash basin.

The plug or valve stopper indicated generally at 34 is formed preferably of one piece of metal material, shaped to form a circular disk or head 35 and a body portion 3B. The head has a beveled edge 31 which seats on the complementary shaped portion of the sleeve. The body 36 has a plurality of spaced apertures 38 which form the discharge openings and which also communicate with the overflow passage. The body is also provided with a plurality of (preferably four) equally spaced trackways, generally indicated at 40, each of which is formed of a vertical slot 42 which communicates with a horizontal slot 44 and an outlet slot 46 which leads outwardly of the body portion. The vertical slot 42 extends below its communicating horizontal slot as at 48, thereby forming a stop or interrupter member 50, to prevent accidental removal of the plug member and to keep it operating in a vertical direction.

The body of the plug springs out adjacent its lower end and when stamped can be made so that the metal portion 52 which forms the bottom of the body can be urged slightly outwardly so that as the plug moves in the sleeve there will be a friction tight lit between it and the sleeve, and the plug will maintain itself in any raised position and will also provide a more iluid type seal when in closed position. The natural resiliency of the metal of the plug by virtue of the slotted portions will increase the frictional t between the plug and sleeve. In Fig. 2, the plug is shown constructed with a taper with the circumference of the body greatest at the bottom. The plug has suitably secured to the top thereof a knob A2l to which is secured the ring 23, by means of which the plug is raised and lowered.

Stamped from the body of the sleeve 28 and bent inwardly at right angles thereto are four fingers 54 which meet and form a cross guide member, generally indicated at 56, and more clearly shown in Fig. 3. The guide member cooperating with the slots 42, 44 and 46 of each of the trackways, serves to position and limit the vertical movement and the horizontal rotation of the plug 34.

The operation of the construction shown in Figs. 1 to 3 is as follows:

The plug 34 canbe initially inserted or'reinserted after its removal by aligning the slots 46 with the guide fingers, then pushing the plug downwardly until it is stopped, then rotating it clockwise so that the slot 44 passes through the guide fingers until same strike the end of the slot, then the plug is pushed downwardly where the slot 42 passes through the guide lingers. The plug is shown in closed position in Fig. l. In normal operation, the plug is moved only in a vertical direction to raise and lower same and the slot 42 will be in engagement with the guide ngers. The portion 50 adjacent the bottom oi the slot 42 will act to prevent any accidental rotation of the plug and will keep it in its straight vertical path. However, should it be desired to remove the plug for cleaning and the like, the plug is raised so that the slot 44 is brought in alignment with guide fingers, then the plug is vrotated counterclockwise so that the slot 44 passes through the fingers until the lingers hit the edge of the sl'ot', then the. plug i's. further raised to permit it tobe-removedf through the outlet slot 48.

With this construction I have provided a plug body and sleeve, each formed of one piece of" material which will have theresiliency to.l maintain the plug in any of its placed positions and which can be operated, inserted and removed with a minimum of effort and time: type of trackway, an unauthorized removal of the plug from the sleeve is difficult, for unless one is familiar with the trackway construction he will cause the plug to move up and down.

Fig. 4' shows a modified construction. The sleeve,l 58 has a: plurali-ty ofguide arms 60- which Support a ring 62. Thefpl-ugv 64 suitably' supports as at 66a pairl of outwardly bowed spring' arms 881 which ride within the ring (i12Y to support and positiom the plug 64 inany oiits raised positions. The plug; has. a plural-ityofv trackways 1:0, similar to.- those described in connection with. plug 34, and thesex opera-te similarly thereto, with the guide armr 601.

In; Fig.. 5, I provide a; sleeve 12 which has a plurality ofl struck-out. lngersI 14, whichv engage the plug 16, to hold same in any raised position. The! sleeve 12 is prcwidedY withf a: pluralityof cross bars 1.8 which. supporta. ring. 8f),` having a keyway 8.2. Theplug; 84 supports` a rod 85 which rides inthe ring 80; The rod. has a key 88'. When it isv desired to remove the; plug from the sleeve, the key 88 isi alignediwithl the keyway, 82 and withdrawn therethrough. Normally the plug will. be

moved; vertically up and down anda'helrt in= any placedi position by virtue'of the friction litv caused by the flngerse '|14 cooperating with the plug'IB.

VIri.-1iigs.x6? and* 7,12' show' another modification. The sleeve 89 has: cross bars 90.' and*` a ring 9i. TheA ring'ha's a keyway,v 92; The: plug; 93 supports are@ 94 secured totheetop of the' plug as'at 95. 'Ilier roda is internally bored as at: 96, and has a slotted' opening,y 91:. suitably anchored in thev rod 'by means of a screw 98 leaf spring member 99 which is bowed outwardly and extends outwardly of said slot,` to-l engage the ring 9k. Thev plug 93 canbe positioned: and maintained'in any such position, by said. means.. Toy remove the plug, it is rotated until the screw 9,8, which also. acts: as a. keyis: aligned; with the Akeywayf 92,4 and then it `is drawn' upwardly throughf sai'd keyway 92.

What I desire to`A secure by Letters Patents is: 1'.
